The Damansara-Shah Alam Elevated Expressway (DASH) is a 20.1 km, 3-lane, dual carriageway expressway that will commence at the Puncak Perdana U10 Shah Alam intersection and serve as a link for Puncak Perdana, Alam Suria, Denai Alam, Kampung Melayu Subang, Jalan Sungai Buloh, RRIM, Kota Damansara, Damansara Perdana and Mutiara Damansara. It will end at the Penchala interchange, linking road users to LDP and SPRINT highways. 12 interchanges will be built along the alignment. The proposed expressway is expected to support rapid developments along the alignment covering U10 Shah Alam, Subang, Kota Damansara and Damansara areas.

Benefits of DASH

As an alternative route for Persiaran Surian at Kota Damansara which has capped its road capacity

The rapid development along Shah Alam and Jalan Batu Arang corridors require an additional road capacity

As Subang Airport becomes the main low cost carrier terminal in 2015, DASH will become an alternative and easier route to the airport

It will act as a link between east and west of Klang Valley by crossing over NKVE and linking existing highways namely GCE, LDP and SPRINT

RRIM’s development in the area is expected to increase population by 300,000 which will cause congestions to the existing routes. DASH will be a solution to this problem
